Description
Die vorliegende Erfindung betrifft eine Pumpeinheit mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a pump unit with the features of the preamble of
Wasserpumpen weisen häufig Gleichstrommotoren auf. Die Gleichstrommotoren umfassen einen Rotor, der mit einer Motorwelle verbunden ist und in einem Gehäuse drehbar gelagert ist. Der Rotor ist mit Permanentmagneten versehen. In dem Rotor ist ein Stator angeordnet, der auf einem Eisenkern eine Anzahl von Wicklungen trägt. Bei geeigneter Ansteuerung erzeugen die Wicklungen ein Magnetfeld, das den Rotor zur Rotation antreibt. Die Wicklungen werden üblicherweise dreiphasig gewickelt und werden dementsprechend mit drei elektrischen Anschlüssen versehen, über die die Wicklungen mit einer Steuereinheit (ECU) verbunden werden können. Diese Steuergeräte werden insbesondere im Motorraum eingesetzt und sind dort erheblichen Temperaturschwankungen ausgesetzt, die zu größeren Druckschwankungen im Inneren des Gehäuses führen können. Zum Ausgleich dieser Druckschwankungen sind aus dem Stand der Technik semipermeable Membranen bekannt, die über eine Entlüftungsöffnung angeordnet Luft und auch Wasserdampf nach außen und innen über die Membran passieren lassen jedoch Wasser in flüssiger Form nicht. Bei Wasserpumpen, die im Motorraum von Straßenfahrzeugen eingesetzt werden, besteht außerdem die Forderung zum Schutz der Pumpen vor von Dampfdruckstrahlern erzeugtem Dampfdruck.Water pumps often have DC motors. The DC motors include a rotor which is connected to a motor shaft and is rotatably mounted in a housing. The rotor is provided with permanent magnets. A stator is arranged in the rotor and carries a number of windings on an iron core. With suitable control, the windings generate a magnetic field that drives the rotor to rotate. The windings are usually wound in three phases and are accordingly provided with three electrical connections via which the windings can be connected to a control unit (ECU). These control units are used in particular in the engine compartment, where they are exposed to considerable temperature fluctuations, which can lead to greater pressure fluctuations inside the housing. To compensate for these pressure fluctuations, semipermeable membranes are known from the prior art which, arranged via a vent opening, allow air and also water vapor to pass through the membrane to the outside and inside, but not water in liquid form. In the case of water pumps that are used in the engine compartment of road vehicles, there is also the requirement to protect the pumps from steam pressure generated by steam pressure jets.
Es ist Aufgabe der vorliegenden Erfindung, eine Pumpeinheit mit einem möglichst einfachen Steckverbinder und mit einem möglichst einfachen Entlüftungselement bereitzustellen.The object of the present invention is to provide a pump unit with the simplest possible connector and with the simplest possible ventilation element.
Diese Aufgabe wird von einer Pumpe mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a pump with the features of
Demnach ist eine Pumpeinheit aufweisend einen Elektromotor mit einer eine Steuereinheit tragenden Leiterplatte, eine mittels des Elektromotors angetriebene Pumpe, ein die Leiterplatte umgebendes Gehäuse, und einen Steckverbinder, der auf der Außenseite des Gehäuses mit einem Flansch befestigt ist, der eine Öffnung des Gehäuses überdeckt und der Kontakte zur unmittelbaren elektrischen Kontaktierung der Leiterplatte aufweist, die die Öffnung des Gehäuses durchsetzen, vorgesehen, wobei der Steckverbinder ein Druckausgleichselement zur Entlüftung des Gehäuses aufweist, welches einen Sinterfilter umfasst. Durch Integration des Druckausgleichelementes in den Steckverbinder, wird der Herstellungsprozess deutlich vereinfacht. Die Verwendung eines Sinterfilters bringt eine deutliche Kostenreduktion gegenüber Membranen. Zudem ist ein Sinterfilter einfach zu Handhaben, wodurch die Anordnung robuster wird. Der Steckverbinder weist bevorzugt einen außerhalb des Gehäuses liegenden Verbindungsbereich für einen Anschlussstecker auf.Accordingly, a pump unit comprising an electric motor with a circuit board carrying a control unit, a pump driven by the electric motor, a housing surrounding the circuit board, and a plug connector which is fastened on the outside of the housing with a flange which covers an opening in the housing and the contacts for direct electrical contacting of the circuit board, which penetrate the opening of the housing, provided, wherein the connector has a pressure compensation element for venting the housing, which includes a sintered filter. By integrating the pressure compensation element in the connector, the manufacturing process is significantly simplified. The use of a sintered filter results in a significant cost reduction compared to membranes. In addition, a sintered filter is easy to handle, which makes the arrangement more robust. The plug connector preferably has a connection area for a connector plug located outside the housing.
Vorzugsweise ist der Sinterfilter in eine erste Öffnung eines sich durch den Steckverbinder erstreckenden Entlüftungskanals eingesetzt. Der Entlüftungskanal verläuft bevorzugt zumindest teilweise parallel und beabstandet zu den Kontakten.The sintered filter is preferably inserted into a first opening of a ventilation channel extending through the connector. The ventilation channel preferably runs at least partially parallel and at a distance from the contacts.

Vorzugsweise ist der Sinterfilter in die erste Öffnung des Entlüftungskanals eingesetzt ist, wobei der Entlüftungskanal das Grundgehäuse von der ersten Öffnung zu einer zweiten Öffnung hin durchsetzt, wobei die zweite Öffnung im Bereich der Öffnung des Gehäuses liegt.The sintered filter is preferably inserted into the first opening of the ventilation channel, the ventilation channel passing through the base housing from the first opening to a second opening, the second opening being in the area of the opening of the housing.
In einer bevorzugten Ausführungsform weist das Grundgehäuse auf der Seite der Kröpfung die erste Öffnung des Entlüftungskanals auf.In a preferred embodiment, the base housing has the first opening of the ventilation channel on the side of the crank.
Vorzugsweise ist der Sinterfilter abgedichtet durch Ultraschallschweißen, Laserstrahlschweißen oder Kleben mit dem Steckverbinder verbunden.The sintered filter is preferably connected to the connector in a sealed manner by ultrasonic welding, laser beam welding or gluing.
Es ist vorteilhaft, wenn der Sinterfilter von einer Schutzgeometrie (
Vorzugsweise weist der Sinterfilter gesinterten Kunststoff auf, der durch feinste Poren hydrophob wirkt.The sintered filter preferably has sintered plastic, which has a hydrophobic effect due to the finest pores.
